I have a 93 325i. One day i went to the store car ran great. when to leave the car started and then died. No power to fuel pump relay. replaced DME and the relay still no start no power to the fuel pump relay. The crazy thing is on the obc if you push the code button it dose not do a thing. I know the DME was bad because i could not get a DTC from it. Put the new one and can get into The DME. Dose the DME have to be programed to the car
